                 Abstract: Bei ̄dou ̄genꎬ the dried rhizome of Menispermum dauricum from the Menispermaceae familyꎬ is an important
                 Chinese medicinal material. In order to clarify the pharmacodynamic substance basisꎬ the methanol extract of the rhizome
                 in M. dauricum was systematically isolated and purified using various chromatographic methods and the structures of
                 isolated compounds were identified. The potential anti ̄inflammatory activity of obtained compounds from M. dauricum
                 was measured in vitro. In this studyꎬ the chemical constituents were separated via silica gel column chromatographyꎬ
                                                                                                 1

                 inflammatory activities of against NO and IL ̄6 production from LPS ̄induced RAW264.7 cells of the chemical components
                 were evaluated in vitro. The results were as follows: (1) Fifteen compounds were isolated from the rhizome of M.

                 daucosterol (15). Among themꎬ compounds 4-7ꎬ 9 and 12 were isolated from Menispermaceae for the first timeꎬ while
                 compounds 1ꎬ 3-11 and 14 were first reported from Menispermum genus. The above compounds were all non ̄alkaloids
                 componentsꎬ including phenolsꎬ lignansꎬ phenanthraquinonesꎬ fatty acids and sterols. (2) Anti ̄inflammatory assay in
                 vitro showed that Compound 12 could significantly inhibited releases of NO and IL ̄6 induced by LPS from RAW264.7

                 study enrich the chemical diversity of the rhizome of M. dauricum and clarifies the active ingredients of its anti ̄
                 inflammatory activityꎬ and provide effective reference for the rational utilization of medicinal plant resources.
